cloudflare-os
Cloudflare
Open-source agent workspace on Cloudflare Workers for chatting with agents, building sandboxed apps and enforcing guardrails.
Key features
- Agent Chat UI: Ask agents to complete tasks with built-in knowledge about how your company operates.
- Gadgets: Agents build small personal apps from scratch in a sandbox that can be safely shared with others.
- Gatekeepers Security Framework: Guardrails for agents and apps so non-technical users can experiment safely.
- Built-in Blueprints: Includes templates such as a slides blueprint for generating decks from a prompt.
- Integrations: Optional GitHub and Google integrations let agents work on repos and documents.
- Local and Cloud Deployment: Run the full stack locally on wrangler and workerd or deploy to your own Cloudflare account.
Best for
- An employee asks an agent to make slides for an upcoming customer meeting.
- A team asks for a collaborative whiteboard app built from scratch as a gadget.
- A product manager generates an issue dashboard for a GitHub repo.
- A user asks an agent to fix typos in an attached Google Doc.
- A company forks the project to build its own governed AI workspace.
- A security team enforces guardrails so non-technical staff can safely build apps.
Comet Browser
Perplexity
An AI-powered, Chromium-compatible web browser from Perplexity focused on agentic search, privacy controls, and a Windows-11-oriented UI.
Key features
- Agentic Search Integration: Integrates Perplexity's agentic search approach to surface AI-driven search results and streamline query workflows within the browser interface.
- Chromium Compatibility: Built to be Chromium-compatible so existing Chrome extensions and web features can work or be adapted for Comet (though specific extension support has had compatibility discussions).
- Privacy and Tracker Controls: Emphasizes privacy features and controls intended to limit tracking and improve private browsing experience, a core element raised by users and extension developers.
- Windows-11-Focused UI: Community and experimental builds (including Electron-based iterations) prioritize a modern UI and UX tailored for Windows 11 aesthetics and workflows.
- Developer & Community Builds: Early releases and community repositories provide pre-release downloads and source builds; developers can run or experiment with local Electron/Node-based builds.
- Extension Compatibility Diagnostics: Public issues and discussions (e.g., AdGuard) show active testing and diagnostics around how ad-blockers and other extensions install and function under Comet's environment.
- Chromium-compatible browser core (Perplexity Comet)
- AI/agentic search integration (Perplexity)
- Windows 11–styled UI/UX focus
- Electron-based prototype with webview and tab support
- Developer-run-from-source workflow (Git, Node, npm)
- Tab overhaul and UI icon assets in prototype
- Early-stage project with active commits and experimental features
- Extension ecosystem is Chromium-like but may require compatibility steps (Manifest V3)
Best for
- AI-driven research workflows where users want agentic search results and follow-up queries without switching between separate apps or tabs.
- Privacy-conscious browsing where users rely on built-in tracker and ad controls to reduce profiling while searching and visiting sites.
- Extension testing and adaptation by extension developers (AdGuard and others) who need to ensure compatibility with a Chromium-compatible but distinct browser build.
- Windows 11 users seeking a browser with a modern, native-feeling UI/UX tailored to the OS aesthetic and interaction patterns.
- Early adopters and developers who want to run pre-release or source builds (Electron/Node) to test features, contribute, or prototype integrations.
- Research and productivity sessions that combine standard web browsing with AI search capabilities to accelerate information discovery.
- Using an AI/agentic search-enabled browser for conversational or context-aware web search
- Privacy-focused browsing within a Chromium-compatible shell
- UI/UX experimentation and prototyping (Electron-based desktop browser shell)
- Testing and adapting browser extensions for a new Chromium-based browser (Manifest V3 compatibility)
- Developer/local builds for testing features: clone repo, npm install, npm run dev
